2013 F150 Amp install help

I recently upgraded the door speakers in my 2013 Scab F150 to Infiniti Kappa 682.11CF all the way around. My truck has sync with the smaller 4 inch screen, I bought a 4-channel Alpine MRP-F300 amp to power the door speakers. I have the speakers installed but I have no idea what to do with the amp. Speakers were easy but can't say I've ever installed an amp before.

Took it to a shop and they wanted to charge me $450 to install the amp. Also tried to charge me $250 for a 8 channel line converter. What exactly do I need for this install? Can I use a 2 channel line out converter for this? The amp runs 4x75 watts @2 ohms and the speakers are 100 rms @2ohms. Any help is appreciated

If you've never done an amp before a 4 channel one into a factory head unit isn't the best place to start.

You will need to get power, ground and turn on lead to the amp. Next will need some sort of line out converter to get the signal to the amp and then have to get the output from the amp to the door speakers either via the factory wiring or running your own.

For those costs could just get a new head unit with more power than the stock one. Are you planning on adding a sub or just wanting to amp the door speakers? You won't likely get a ton more low end. To get that you really need some sort of a sub/amp

You will need to tap your existing speaker wires with a line out converter. All 4 if you want to fade or just 2 if you don't. Then you will need to run new speaker wire from the amp back to the speakers. You will also need a turn on wire for the amp from your fuse box and a 12V wire from your battery. RCA cables from the line out converters to the amp

Wow..The guy just wants to install an Amp and everyone wants to figure out how to swap his head unit. LOL....

To answer the OPs question, it's really simple. You need to provide the amplifier with 4 things:

1 - Power/Ground (Power preferably from the battery. Ground from the chassis near the Amp)
2 - Remote power on signal
3 - High level or low level inputs form your head unit (Low level is better)
4 - Speaker wires out from your new Amp to the speakers

The easiest way to get #2, #3 and even #4 done is to buy one of these:

This connects in-line between your factory head unit and factory wiring connectors requiring NO cutting. It will provide you 4 - low level line out connections for your amp as well as a remote power wire AND a way for you to wire the amp to your new speakers without cutting a single factory wire.

For #1, Run a 4ga wire directly from your battery to the rear of the truck behind the rear seat and use a distribution block to run a smaller gauge (8ga) to your new Amp. this will allow you to add a sub woofer at some point in time if you want to. For the ground, find a good place to drill into the back of the cab for a nice clean ground.

For the speakers, you can actually run 4 new speaker wires from the Amp back up to the harness on the PAC AOEM-FRD24 and cut the high level out speaker wires using them instead of running all new stuff to the speakers. that way, if you decide to sell or trade-in, you can remove everything quick and clean.

Its a really easy job if you take your time and have all of the piece parts ready before you tear into everything. Just make sure you have the Power/Ground wire, the low level RCA cables (you'll need 2 - two channel cables. 14' will do). Buy 100' of 14Ga speaker wire, a good crimping tool and lots of butt connectors or you can solder everything if you want.
